The formula
credits = audio_gen_price × (music_tracks + sound_effects)- audio_gen_price
- a flat 2 credits per generation on Suno Sounds V5.5 — the same meter whether the prompt describes a song or a single sound effect, and unaffected by the video's own length.
- music_tracks + sound_effects
- every audio item the video needs, counted as flat units — 1 music bed and 3 effects here. This is additive: each new sound is one more flat charge, never a rate applied to the whole clip.
Worked example — One music bed plus 3 sound effects for a single video
- 1.items: 1 music + 3 effects = 4
- 2.4 × 2
= 8 credits, plus one editor export to lay them onto the video
The additive route the native-audio toggle formula only sketches
One formula on this hub documents the OTHER way a clip gets audio: a native-audio video model, where turning sound on replaces the per-second rate for the whole clip. This page prices the additive route that formula only sketches — generating the music and the sound effects as their own items and laying them onto a video that was rendered silent.
Both the music bed and every sound effect land on the exact same flat meter — Suno Sounds V5.5 at 2 credits a generation, whether the prompt asks for a song or a single door-slam. There's no separate "sound effect" price in the catalogue; it's the same audio-generation call with a different prompt.
The two routes are not close. An 8-second shot with native audio on VEO 3.1 costs 160 credits more than silent — for that alone, this page's whole worked example (one track, three effects) could run 80 times over.
Item counts, and the toggle premium compared
Every figure below is computed from Versely's live price matrix — the same matrix the app quotes you from before it charges. These are prices, not verdicts: the buyer's guides are where models get ranked.
How many audio items, and what they cost
Every row uses the same 2-credit flat rate — only the item count changes.
| Audio items | What's in it | Credits |
|---|---|---|
| 1 | Music bed only | 2 |
| 2 | Music bed + 1 effect | 4 |
| 4 | Music bed + 3 effects | 8 |
| 7 | Music bed + 6 effects | 14 |
Each additional sound effect is one more flat charge — there's no bundle price and no discount for buying several.
The additive route versus the native-audio toggle
Comparing this page's 4-item worked example against the native-audio toggle formula's own 8-second worked example.
| Route | What it buys | Credits |
|---|---|---|
| Additive (this page) | 1 music bed + 3 sound effects | 8 |
| Native audio toggle on VEO 3.1 | just turning sound on for 8s of clip | 160 |
The toggle premium alone is 20× this page's whole worked example — and the additive route's items don't scale with the video's length the way the toggle's per-second rate does.
What changes a music-and-effects bill
Number of sound effects
Linear at 2 credits each — the only real variable in the additive total.
Choosing additive over native-audio toggle
Replaces a per-second rate multiplied across the whole clip with a handful of flat charges — dramatically cheaper on anything but the shortest clips.
Reusing one track across several clips
A single generated music bed can score multiple videos at no extra charge.
The attach step
Laying the finished audio onto the video is an editor export charge, not an additional per-item fee.
What this formula does not cover
- Attaching the generated audio to the video — an editor export charge, priced on its own page.
- Extending a track or writing custom lyrics before generating it — separate tools, each without a distinct catalogue price of its own.
- Native audio generated by the video model itself, an entirely different toggled-rate formula, priced on its own page.
How many audio generations a month of credits buys
A Monthly plan's 580 credits covers 290 individual audio generations — enough for 72 videos' worth of this page's 4-item worked example.

Frequently asked questions
Is a sound effect cheaper to generate than a full song?+
No — the catalogue has no separate sound-effect price. Music and sound effects generate on the identical flat 2-credit meter, whatever the prompt describes.
Is it cheaper to add music and SFX separately, or use a native-audio video model?+
Separately, in almost every case. This page's 4-item worked example costs a fraction of just the audio-on premium on the native-audio toggle formula's own 8-second example.
Does a longer video cost more to score with music and effects?+
Not through this formula — each generation is a flat charge independent of the video's length. A native-audio toggle's per-second rate is what scales with duration; this route doesn't.
Can one music track cover more than one video?+
Yes — nothing ties a generated track to a single video. Reusing it across several clips doesn't generate it again or charge again.
What does it cost to attach the finished audio to my video?+
That's a separate editor export charge, not an additional per-item audio fee — priced on the editor's own export page.
Different job, different arithmetic
These are not variations on the formula above — each one meters something else entirely.
What does an AI video with sound cost?
credits = rate_per_second(audio on | audio off) × secondsIt flips the per-second rate with an audio toggle rather than adding a separate fee.
What does an AI music video cost?
credits = music_price + (clip_tier_price × clips), clips = ceil(song_seconds ÷ 6)It stacks one flat music charge with many repeated per-clip video charges, where a single ad's stack never repeats a stage.
What does an AI voiceover cost for my script?
credits = ceil( characters ÷ 1,000 × 12 )It meters the characters you type, not the seconds you get back.
